Self-Hosted AI vs Cloud AI Hosting

The five ways to host an AI application in 2026 β€” managed model APIs, inference API providers, runtimes in your own cloud account, on-premise and air-gapped β€” and what you operate versus what the provider operates in each

On ibl.ai you own all the code and the data, run it model-agnostic across any LLM, and pay with no per-seat pricing β€” so you can deploy anywhere, from your own cloud to a fully air-gapped network.

What's the difference between Self-Hosted AI (ibl.ai) and Managed Cloud AI Hosting?

Self-hosted AI means the model runtime and the application around it run on infrastructure you control. Managed cloud AI hosting means a provider operates one or both. On ibl.ai you own all the code and the data, and the platform runs on any of the hosting options below.

The options, from most to least managed: managed model APIs (Amazon Bedrock, Azure OpenAI in Microsoft Foundry, Google Vertex AI, the OpenAI API); inference API providers for open-weight models (Together AI, Fireworks, Groq, DeepInfra, Baseten).

Then: open-source runtimes in your own cloud account or VPC (vLLM and SGLang, Apache-2.0; Ollama and llama.cpp, MIT); on-premise GPU servers; and fully air-gapped networks. Hugging Face TGI was archived in March 2026 and now points users to vLLM, SGLang and llama.cpp.

The trade is operations for control. Managed hosting removes GPU work and bills per token; self-hosting takes the provider out of the data path and is the only air-gapped route. ibl.ai is model-agnostic, has no per-seat pricing, and is family-owned and operated from New York, NY.

How do self-hosted AI and cloud AI hosting compare, layer by layer?

What You Operate vs What the Provider Operates

CriteriaSelf-Hosted AI (ibl.ai)Managed Cloud AI Hosting
GPUs and model serving

You run vLLM, SGLang, NVIDIA NIM or Ollama on your GPUs β€” or the platform calls a managed API for that workload.

The provider runs capacity, scaling, model upgrades and failover.

Agents, memory, RAG and logs

On ibl.ai, in the database you operate: conversations, memories, datasets and eval traces.

Your app's own store plus provider-side stateful features β€” OpenAI's Responses API keeps state 30 days by default.

Where prompts and outputs travel

Inside your network for self-hosted models; to a provider you choose, per workload, when not.

To the provider's region; Azure Global and DataZone deployments may process in other geographies in the zone.

Air-gapped operation

Supported: the full platform with local models and zero external API calls.

Not possible β€” a managed endpoint needs network reachability.

Cost Shape

CriteriaSelf-Hosted AI (ibl.ai)Managed Cloud AI Hosting
Fixed cost to start

GPU servers or reserved cloud instances, paid whether or not they are busy.

Near zero: on-demand per-token pricing with no commitment.

Cost at sustained high volume

Flat GPU cost amortised over every token once utilisation is high.

Scales linearly with tokens; Bedrock batch is 50% lower and provisioned throughput is hourly, with 1- or 6-month terms.

Seat licensing

ibl.ai has no per-seat pricing; usage against caps you set.

Model APIs are per token, not per seat β€” the per-seat bill comes from SaaS apps layered on top.

Capability

CriteriaSelf-Hosted AI (ibl.ai)Managed Cloud AI Hosting
Frontier proprietary models

Reached through the same managed APIs, routed from your platform; closed weights cannot be self-hosted.

The only place the newest closed models run, often on launch day.

Elasticity and time to first deployment

Capacity is the GPUs you provisioned; infra-cli automates the platform install.

An API key and minutes; bursts absorbed by the provider.

Model and provider portability

Switch any agent between self-hosted and managed models without rewriting the application.

Bound to one provider's catalog, SDK and stateful features unless you add an abstraction.

Which AI hosting option fits which workload?

What are the main AI hosting options in 2026?

Self-Hosted AI (ibl.ai)

Self-hosted options: open-source runtimes such as vLLM, SGLang, Ollama and llama.cpp in your cloud account or VPC, on-premise GPU servers, and air-gapped networks with no outbound path.

Managed Cloud AI Hosting

Managed options: hyperscaler model APIs (Amazon Bedrock, Azure OpenAI, Google Vertex AI), the model labs' own APIs, and inference API providers serving open-weight models.

Verdict

Most enterprises end up using several. The useful decision is per workload, not one hosting model for the whole organization.

Is self-hosting or cloud AI hosting cheaper?

Self-Hosted AI (ibl.ai)

Self-hosting has a fixed GPU cost that wins once utilisation is high and steady, because each extra token is close to free.

Managed Cloud AI Hosting

Managed hosting has no fixed cost and wins for spiky or low volume; Bedrock adds a 50% batch discount and hourly provisioned throughput for steadier loads.

Verdict

Compare the monthly token bill against the cost of the GPUs that would serve it at your real utilisation. Below that break-even, rent; above it, own.

Can you mix self-hosted and cloud AI hosting?

Self-Hosted AI (ibl.ai)

On ibl.ai the platform β€” agents, memory, data, audit β€” stays on your infrastructure while each agent's model can be a local runtime or a managed API.

Managed Cloud AI Hosting

Hyperscalers support hybrid patterns inside their own cloud, such as VPC endpoints, but the model endpoint remains theirs.

Verdict

Hybrid is the common answer: own the application layer and the data, and pick the model host per workload and per sensitivity.

Should my organization self-host AI or use cloud AI hosting?

Prototypes, pilots and spiky workloads

Managed Cloud AI Hosting

No fixed cost and instant capacity make managed model APIs the right first step.

Steady, high-volume workloads on open-weight models

Self-Hosted AI (ibl.ai)

Once GPUs stay busy, a flat hardware cost undercuts per-token pricing, and the data never leaves your network.

Defense, government and air-gapped environments

Self-Hosted AI (ibl.ai)

No managed endpoint can serve a network with no outbound path; only self-hosted models can.

Most enterprises running many AI workloads

Either

Own the platform and the data, then host each model wherever its cost, capability and sensitivity point.

How do I move from cloud AI hosting to self-hosted AI on ibl.ai?

Managed cloud AI β†’ self-hosted on ibl.ai

medium difficulty

Timeline: Two to six weeks for the platform; model moves happen workload by workload

  • Inventory: list each workload's model, monthly tokens and data sensitivity; move open-weight-eligible, high-volume or sensitive ones first.
  • Platform: provision ibl.ai with infra-cli in your own AWS or GCP account, or bootstrap existing servers on any cloud or bare metal.
  • Models: keep managed providers as organization LLM keys for frontier workloads, and serve open-weight models locally via NVIDIA NIM, Ollama or vLLM.
  • Agents and RAG: recreate prompts as agents and re-ingest documents as datasets, so retrieval indexes live on your infrastructure.
  • Eval: run the same benchmark against the managed and self-hosted model before switching, with LLM-as-Judge scoring.
  • Air-gapped: for networks with no outbound path, deploy with local model weights only and no external providers configured.

Self-hosted β†’ managed cloud AI

low difficulty

Timeline: Hours per workload

  • Add the provider's key in the organization's LLM settings and switch the agent's model β€” the application layer does not move.
  • Check region, retention and abuse-monitoring terms for the chosen endpoint before routing sensitive data.
  • Reasonable for frontier-model workloads or when GPU utilisation is too low to justify the hardware.

Where does ibl.ai fit alongside Managed Cloud AI Hosting?

ibl.ai is the agentic AI platform where you own all the code and the data. You self-host the entire stack inside your own perimeter, run it model-agnostic across any LLM and switch anytime, and pay by usage with no per-seat pricing β€” so you can deploy anywhere: your cloud, on-premise, GovCloud, or fully air-gapped.

ibl.ai is the part of an AI stack that should never be rented: agents, memory, datasets, evaluation and audit, on infrastructure you control, pointed at whichever model host fits each workload. Agentic OS runs in your cloud account, on-premise or air-gapped, and our Air-Gapped AI and Amazon Bedrock services cover both ends of the hosting spectrum. You own all the code and the data, whichever GPUs serve the tokens.

1.6M+ users across 400+ organizations run the platform this way, including NVIDIA, MIT, and Syracuse University.

ibl.ai is family-owned and operated from New York, NY β€” a U.S.-headquartered, domestically-owned long-term partner, not a vendor that sells licenses and moves on.
